WebTypically, the nucleus is the most prominent organelle in a cell. The nucleus (plural = nuclei) houses the cell’s DNA in the form of chromatin and directs the synthesis of ribosomes and proteins. Let us look at it in more detail ( Figure 3.11 ). Figure 3.11 The outermost boundary of the nucleus is the nuclear envelope.
